Still waiting for the source of Cain saying the word “racist”
...or did you make it up?
The Miami Herald quotes Cain as saying, “Yes, it was painted over, but how long ago was it painted over? So I’m still saying that it is a sign of racial insensitivity on Perry’s part.”
There. done your work for you. Why wait on someone else?
Incidentally the term ‘niggerhead’ is a term for a type of rock.
Look that up when you have time.
